-----------------------------------------------------------------***----------------------------------------------------------------ABSTRACT Highways are such an intricate part of connectivity in India that there is always a need of highway construction or maintenance of existing highway. Due to lesser availability of fund use of waste material from industries and agricultural fields is much in use. This experimental work briefly describes the use of locally available rice husk ash in soil stabilization along with cement. Rice husk ash helps in improving the desired properties of soil and minimizes the amount of waste to be deposited in environment causing environmental pollution. Rice husk ash is quite easily available and is very low in cost, due to day by day increase in cost of stabilizers like cement, lime and other admixer’s use of rice husk ash can result in project completion optimally. The soil sample used is clay which requires to be strengthened due to presence of high plasticity,this soil sample is strengthened by using varying proportion of rice husk ash and cement. Various tests were conducted to analyze the effect of rice husk ash on optimum moisture content, maximum dry density, and California bearing ratio. Results shows increase in optimum moisture content but decrease in maximum dry density, Along with increase in California bearing ratio, from the observations it can be seen that 10% of rice husk ash and 6% of cement results in maximum improvement in desired soil properties. Due to its low cost and effectiveness in increasing the California bearing ratio of soil this method of soil stabilization is strongly recommended.

1. INTRODUCTION
Utilization of farming waste have decreased the environmental hazards, Rice is that primary supply of food for billion peoples across the planet. At the present around 600 metric tons of paddy made annually. Rice husk could be a main agronomic by product acquired from the food crop of paddy. For each four heaps of rice one ton is of rice husk made. Burning of rice husk generates almost 15-20% of its weight as ash. The studies on physical and chemical properties of rice husk ash have revealed that RHA can’t be used alone for stabilization of soil attributable to the dearth of building material properties. The
Soil stabilization means improvement of the stability or bearing capacity of soil by the means of controlled compaction, proportioning and or addition of suitable modifiers or stabilizers. Since there is increase in construction there is always a need of material low in cost and environment friendly which can impart desired strength with effectiveness in construction. Past studies have revealed that rice husk can be used effectively in expansive soils that are having high plasticity. © 2017, IRJET
